BACKGROUND OF THE INVENTION

The proliferation of electronic and electrical devices is a key factor fueling an ever-increasing demand for additional alternating current (AC) outlets at home, on the road, and in the workplace. Often there are too many devices and not enough outlets. Additionally, devices including calculators, phones, and laptops use AC to direct current (DC) power converters (commonly called wall-bricks) to connect to AC power outlets. Due to their non-standard bulky form-factors, wall-bricks often take up more than one outlet, exacerbating outlet-shortage problems and driving users to seek solutions.

A popular remedy is to use multi-outlet power strips. However, these power strips provide an ineffective solution because they fail to adequately address all of the problems created by, and associated with, the increasing prevalence and use of wall-bricks.

For example, a user who owns six devices buys a power strip. While connecting the equipment, the user realizes that two devices use wall-bricks. Upon plugging the bricks into the power strip, the user discovers that only two or three of the six outlets remain open, leaving at least one outlet short. After spending $25-$200, the user expected to be able to use all the outlets, but now must buy one or more additional power strips to plug-in the remaining devices.

Low-cost power strips provide additional outlets, but do not adequately condition or stabilize incoming power, increasing the risk of equipment malfunction or outright failure. Moderate to high priced surge protectors perform well, but bulky wall-bricks often cover multiple outlets, reducing the number of devices that can be connected.

Additionally, wall-bricks often generate heat and electrical interference in addition to passing along the ambient AC conducted sags, spikes, surges, and noise generated by the power-grid and carried along AC power-lines throughout industrial, office, and residential settings. Electrical power disturbance events cause data loss and damage equipment. Wall-bricks pack and travel poorly, create cable-clutter, and are an eyesore.

Damaged equipment and downtime costs are a growing concern among users. As technology has advanced, business, commerce, home, and industrial users have become increasingly dependant on the health of the networks that supply and manipulate data and information. Additionally, the growing emphasis on network speed and the sheer volume of transactions that can take place in a fraction of a second make the prospect of downtime that much more ominous. The cost to business and industry of human or naturally caused power surges and outages has become substantially more detrimental.

It is clear from the statistical evidence that power conditioning is a vital issue and one whose importance is only going to increase. Clean, constant, noise-free power is required to ensure the proper operation, and to protect the delicate circuitry, of today's electronic and electrical devices.

Presently, systems and methods are needed that simultaneously solve outlet-shortage and transient voltage surge and noise problems. New systems and methods are needed to eliminate wall-brick issues and other identified problems.

DETAILED DESCRIPTION

The automatic sensing power systems and methods enable alternating current (AC) to direct current (DC) power conversion, DC to DC power conversion and supply, data communication, and power management. In one embodiment, an automatic sensing power system (ASPS) component is embedded in an electronic device, such as a laptop computer, and a power delivery component resides in an ASPS, such as a power strip or a receptacle.

In one embodiment, upon connection to the ASPS, the laptop communicates its power requirements to the ASPS via a power cord. The ASPS processes the request and supplies the appropriate power. Inexpensive low voltage electrical cords and modular adapters replace the wall-bricks typically supplied with cell and desk phones, personal digital assistants (PDAs), computers, mobile phones, digital cameras, cordless drills, fax machines, and other electrical devices. The ASPS is programmable and upgradeable.

The ASPS solves many problems currently encountered by home, office, and industrial consumers. The ASPS couples with single and multi-receptacle plug-in and hard-wired surge suppression devices, AC/DC power converters and transformers, and a wide-range of electronic and electrical appliances, tools, and devices.

In one embodiment, the ASPS eliminates wall-bricks by placing modular DC receptacles in a power system. The power system has AC and DC receptacles in one unit, thereby eliminating the need for multiple power strips. The power system includes communication and networking interfaces and systems over which communications may be transmitted, such as through Bluetooth, Ethernet, Firewire, and/or a USB connection. In this embodiment, the ASPS includes expanded data line protection, such as for cable, DSL, Ethernet, and modem protection. In another embodiment, the ASPS integrates gateway, network, and router capabilities. Another embodiment incorporates data communication over a broadband connection. In one example, electronic devices communicate with and through the power system via a DC connector or an AC connector.

In another embodiment, the ASPS includes a line-cord device with a detachable wall plug device. Once detached, the wall-plug device can be moved between rooms or offices or taken on the road to replace wall-bricks.

FIGS. 1-3 depict an exemplary embodiment of an automatic sensing power system (ASPS). In the embodiment of FIG. 1, the ASPS 102 includes a line-cord device 104 and a detachable wall plug device 106. The line-cord device 104 has a housing 108, and the detachable wall plug device 106 has a housing 110. In other embodiments, the ASPS 102 may be only a wall plug device, only a line-cord device, or a combination thereof. The ASPS 102 also may be embodied in other forms, such as a modular wall plug permanently installed or removably installed in place of a wall receptacle, an alternating current (AC) wall receptacle, or another AC or direct current (DC) device.

The ASPS 102 may be incorporated in, for example, an electronic device, such as a computer, a laptop computer, a pocket PC, a personal digital assistant (PDA), a mobile phone, a recording device, or another electrical device. As used herein, an electrical device means a device that operates using electricity, including AC and/or DC electricity. Similarly, electrical devices may use a portion of the ASPS systems identified below, including those electrical devices previously listed and other electrical devices.

Referring again to FIGS. 1-3, the line-cord device 104 includes one or more AC receptacles 112-126. Each AC receptacle 112-126 includes a power control/indicator 128-142, such as a physical or logical on/off switch used to enable or disable power flow to the associated AC receptacle 112-126. In one embodiment, the power control/indicators 128-142 are lighted switches. In another embodiment, the lighted switches are lighted when power is enabled to the AC receptacle, and not lighted when power is not enabled to the receptacle. In another embodiment, the power control/indicator 128-142 is only an indicator, such as a light, and is not used to enable or disable power to the associated receptacle 112-126. For example, a processor within the ASPS 102 may be used to enable or disable power to a receptacle, and the power control/indicator 128-142 indicates whether or not power is enabled or disabled for that receptacle. In still another embodiment, the power control/indicator 128-142 is configured to enable and disable power to the associated receptacle, and the power control/indicator includes an indicator, such as a light, to indicate whether power is enabled for the receptacle either by the physical power control or by a processor or other system or method.

The line-cord device 104 also includes one or more automatic sensing (AS) DC receptacles 144-148. The AS DC receptacles 144-148 may be used by devices for which the power requirements, including voltage and/or amperage requirements, will be automatically determined. The power requirements for the electrical device connected to the AS DC receptacles 144-148 then will be provided to the electrical device, as will be explained more completely below.

The AS DC receptacles 144-148 also have an associated power control/indicator 150-154 such as a physical or logical on/off switch used to enable or disable power flow to the associated DC receptacle 144-148. In one embodiment, the power/control indicators 150-154 are lighted switches. In another embodiment, the lighted switches are lighted when power is enabled to the DC receptacle, and not lighted when power is not enabled to the receptacle. In another embodiment, the power control/indicator 150-154 is only an indicator, such as a light, and is not used to enable or disable power to the associated receptacle 144-148. For example, a processor within the ASPS 102 may be used to enable or disable power to a receptacle, and the power control/indicator 150-154 depicts whether or not power is enabled or disabled for that receptacle. In still another embodiment, the power control/indicator 150-154 is configured to enable and disable power to the associated receptacle, and the power control/indicator includes an indicator, such as a light, to indicate whether power is enabled for the receptacle either by the physical power control or by a processor or another system or method.

In the embodiment of FIGS. 1-3, the line-cord device 104 also has a main power control/indicator 156. The main power control/indicator 156 is used to enable or disable power to the line-cord device 104. In one embodiment, the main power control/indicator 156 includes a fuse device configured to disable power to the line-cord device 104 if power to the line-cord device exceeds selected voltage and/or selected amperage requirements. In another embodiment, the main power/control indicator 156 includes a surge protection device and/or other voltage and/or amperage protection devices.

The ASPS 102 also includes an electrical connector 158 configured to transfer power from an electrical supply to the ASPS 102. In one embodiment, the electrical connector 158 also is configured to communicate data to and from the ASPS 102.

As best depicted in FIGS. 1 and 3, other data communication connections 172 and 174 are used to communicate data to and from the ASPS 102 in various formats and using various protocols. In one example, the data connections 172-174 include one or more cable ports, such as an in and out cable connection. Other types of data connections, networking connections, device connections, and/or device controllers may be used.

Referring again to FIGS. 1 and 2, the detachable wall plug device 106 includes AS DC receptacles 176-180. The AS DC receptacles 176-180 have an associated power control/indicator 182-186. The AS DC receptacles 176-180 and the power control/indicators 182-186 are the same as those described above.

The detachable wall plug device 106 also includes one or more electrical connectors 188-190, such as module plugs, used to transfer power to the wall plug device. The electrical connectors 188-190 connect to receiving connectors 192-194 in the line-cord device 104. AC and/or DC power is transmitted from the line-cord device 104 to the wall plug device 106 via the electrical connectors 188-190 and the receiving connectors 192-194. In some embodiments, communications, including control instructions and/or data, are transmitted from the line-cord device 104 to the wall plug device 106 via the electrical connectors 188-190 and the receiving connectors 192-194. It will be appreciated that one or more electrical connectors may be used. Additionally, while a standard 3-prong wall plug is depicted in FIGS. 1 and 2, other electrical connectors may be used.

In one embodiment, the wall plug device 106 includes a fuse device. In another embodiment, the wall plug device 106 includes a surge protection device and/or other voltage and/or amperage protection devices. In another embodiment, the wall plug device 106 includes a reset control.

In one embodiment, the ASPS 102 includes a grounded indicator 196 and/or a protected indicator 198. The grounded indicator 196 indicates that the ASPS 102 is properly grounded to an electrical supply, such as to an AC receptacle. Therefore, the ASPS 102 should provide properly grounded electrical connections for electrical devices connected to the ASPS.

The ASPS 102 also may include a protected indicator 196 in other embodiments. The protected indicator 198 indicates that surge protection and/or noise filtration systems and/or circuits are functional. In other embodiments, the wall plug device 106 includes a grounded indicator and/or a protected indicator.

FIG. 4 depicts an exemplary embodiment in which an ASPS 102A communicates with one or more electrical devices 402, including a computer 404, a PDA 406, a mobile phone 408, and/or another electrical device, via an electrical connection 410 and/or a data communication connection 412. The electrical connection 410 and/or the data communication connection 412 are depicted as logical connections. The data communication connection 412 is optional for some embodiments. In one embodiment, the electrical connection 410 and/or the data communication connection 412 both may use a single physical connection over which both power and data communications are transmitted. In another embodiment, the electrical connection 410 and/or the data communication connection 412 may use one or more physical connections.

The ASPS 102A also is connected by a connection 414 to a power system 416 and/or a communication system 418. In one example, the power system 416 is a power source for AC power. In one embodiment of FIG. 4, the ASPS 102A communicates both power and data over the same connection 414 to the power system 416. In this example, the power system 416 includes one or more of a private power system and/or a public power system. In this example, data communications are transferred to other electrical devices, such as to communications devices or computers, via the power system 416. In another example of this embodiment, data communications are transmitted to other electrical devices, such as communication devices and/or computers, via the communication system 418.

In one example, the electrical connection 410 is an AC connection. In another example, the electrical connection 410 is a DC connection. In another embodiment, the electrical connection 410 is a two-wire DC cord with a modular connector on one end and a barrel connector on the other end. In another embodiment, the electrical connection 410 is a two-wire DC cord with a modular connector on one end and configured to accept one or more adaptive connectors on the other end.

In another example, the connection 414 is connected to an electrical supply, such as an AC receptacle in a home, office, or business, to a private or public power system. In one example, the connection 414 to the electrical supply connects to a public electrical power grid. Private circuits generally connect to the electrical grid via a service entrance panel or subpanel device that may or may not require the AS communication interfaces described herein.

In another embodiment, an automatic sensing (AS) processing system, as described more completely below, resides on the ASPS 102A. In another embodiment, an AS processing system resides on the electrical device 402. In another embodiment, an AS processing system does not reside on the electrical device 402.

In still another embodiment, the electrical device 402 includes one or more of an Ethernet device, a cable device, a digital subscriber line (DSL) device, a satellite device, a dial-up device, an internet protocol (IP) device, or another device configured to communicate data, including voice communications converted to data and transferred as data via the connection 414. In still another embodiment, the data communications are transferred via the power system 416 and/or the communication system 418 to another electrical device, such an Ethernet device, a cable device, a DSL device, a satellite device, a dial-up device, an IP device, or another device configured to transmit or receive communications.

FIG. 5 depicts an exemplary embodiment of an automatic power system (APS). The APS 502 of FIG. 5 includes an automatic sensing power system (ASPS) 102B, an electrical supply 504, an electrical device 506, and a computing device 508. The ASPS 102B is used to automatically determine the power requirements of the electrical device 506, including voltage and/or amperage requirements, and supply the appropriate power to the electrical device.

In this embodiment, the electrical device 506 does not have a power converter. Instead, the electrical device 506 includes a simple electrical connector between the ASPS 102B and the electrical device. The electrical connector is not a bulky power converter, such as a wall brick. The connector may be a standard power conducting wire, such as those used for a laptop computer, a PDA, a mobile telephone, or another electrical device (without the power converter).

The ASPS 102B receives power from the electrical supply 504. Upon determining the power requirements, the ASPS 102B supplies the correct power to the electrical device 506.

The ASPS 102B communicates with the computing device 508. The computing device 508 may be a computing device, data device, or another device configured to communicate with the ASPS 102B.

In one embodiment, the computing device 508 receives status data from the ASPS 102B, including faults, breakdowns in processes, if any, surge identifications, and other status information. In another embodiment, the ASPS 102B receives data from the computing device 508. In one example, the ASPS 102B receives control data, such as configuration data, from the computing device 508.

In one example, a user uses the computing device 508 to load the power requirements of the electrical device 506 to the ASPS 102B. The ASPS 102B stores the power requirements and uses the power requirements to provide the appropriate power levels, including voltage and/or amperage levels, to the electrical device 506.

In another example, the ASPS 102B receives data from the computing device 508. The computing device 508 is configured to transmit power requirements for the electrical device 506 to the ASPS 102B. In this example, the ASPS 102B is configured to assign a particular receptacle, such as a particular DC or a particular AC receptacle, to the electrical device 506. In this example, a user may plug the electrical device 506 into a particular receptacle in the ASPS 102B, and the power requirements will be transmitted to the electrical device 506.

In one example, the computing device 508 is configured to enable the particular receptacle for the electrical device 506. In this example, the computing device 508 also is configured to disable one or more other receptacles, including one or more other AC receptacles and/or DC receptacles. In this example, disabling one or more receptacles provides a safety feature so that the electrical device 506 is not inadvertently plugged into a receptacle with the wrong power requirements, which may result in damaging the electrical device. In this example, an indicator light may indicate whether the receptacle is enabled or disabled to receive power and/or to transmit power to an electrical device.

The ASPS 102B may receive configuration data and/or control data to configure one or more receptacles. For example, the ASPS 102B may configure a first receptacle for a mobile telephone and a second receptacle for a computer. In this example, the first receptacle would provide the correct power requirements to the mobile telephone, and the second receptacle would provide the correct power requirements to the computer.

In the above example, the electrical device 506 does not require an AS processing system, as described more completely below. This embodiment provides flexibility to the user for devices not having the AS processing system.

It will be appreciated that the configuration data and/or control data may be provided to the ASPS 102B in a variety of ways. In one embodiment, the ASPS 102B receives configuration data identifying a model of a particular electrical device 506, such as a device name and/or a model name or number or another identifier. In this example, data identifying particular electrical devices and their power requirements reside on the ASPS 102B. In this example, the ASPS 102B performs a search, look up, or other process to identify the particular electronic device model and its power requirements from the data stored on the ASPS. The ASPS 102B then can provide the correct power to the electrical device 506.

In another embodiment, the ASPS 102B is configured to receive the particular power requirements, including voltage and/or amperage requirements, directly from the computing device 508. In this example, the ASPS 102B is not required to perform a search, look up, or other processing operation to identify a particular electrical device's power requirements. In this example, after receiving the configuration information, the ASPS 102B configures a particular receptacle for the power requirements.

FIG. 6 depicts another exemplary embodiment of an APS 502A. In this embodiment, the electrical device 506A includes an AS processing system. In the embodiment of FIG. 6, power is transmitted from the ASPS 102C to the electrical device 506A. Additionally, data is communicated between the ASPS 102C and the electrical device 506A.

It will be appreciated that the power and the data may be transmitted over the same physical connection, one physical connection for the power and another physical connection for the data, or multiple physical connections for the power and/or data.

In one embodiment of FIG. 6, the ASPS 102C identifies that an electrical device 506A has been plugged into one of the receptacles. This identification may be made through hardware, software, firmware, or other methods. In one example, the electrical device 506A makes a circuit when the electrical device is plugged into the receptacle. In another example, the electrical device 506A causes the receptacle to transmit a signal when the electrical device is plugged into the receptacle.

In one example, the electrical device 506A generates a power request upon being connected to the receptacle. In one example, the request includes an identification of the particular electrical device. In another example, the request includes specific power requirements for the electrical device 506A.

The ASPS 102C receives the request and determines the power requirements for the electrical device 506A. In one example, the ASPS 102C identifies the particular electrical device 506A and searches its data, such as through a look up, a search, or other determination, to identify the power requirements for the electrical device 506A. The ASPS 102C provides the appropriate power, including the appropriate voltage and amperage, to the electrical device 506A.

In another example, the ASPS 102C receives a request for power from the electrical device 506A. In this example, the request includes the specific power requirements. In this example, the ASPS 102C is not required to perform a look up, search, or other determination to identify the power requirements for the electrical device 506A. The ASPS 102C provides the power to the electrical device 506A according to the power requirements.

FIG. 7 depicts an exemplary embodiment of one or more processes occurring in the ASPS 102D, the electrical device 506B, and the electrical device 506C. The ASPS 102D communicates with a computing device 508B, and the ASPS 102D receives power from the electrical supply 504.

The ASPS 102D has an AS processing system 702. The AS processing system 702 controls the operations of the ASPS 102D, including data storage, power conversion, enabling and/or disabling receptacles, generating the correct power to each receptacle, communicating with electrical devices 506B and 506C, and communicating with the computing device 508B.

In one embodiment, the AS processing system 702 stores data in, and retrieves data from, the storage device 704. The storage device 704 may include, for example, RAM, ROM, EPROM, EEPROM, Flash storage, or another storage device.

The processor 1002 receives a signal from the switch detector when a mating barrel connector is connected to the connector of the DC receptacle.

In one example, the switch detector has a switch lead that is connected to a ground lead when no device is plugged into the barrel connector. The switch lead also is connected to the processor 1002, and a switch detector signal is transmitted via the switch lead to the processor. When the switch lead is connected to ground, the processor 1002 reads the switch detector signal as a logic 0, which corresponds to ground. When an electrical device is connected to the barrel connector, the switch lead is disconnected from the ground lead. The processor 1002 reads the switch detector signal as a logic 1, which indicates an electrical device is connected into the barrel connector of the DC receptacle.

In one embodiment, an optional switch (not shown) is included between the DC to DC regulator 1018 and the DC receptacles 1030. The optional switch enables a user to turn a selected one or more of the DC receptacles 1030 on or off. In one example, each optional switch includes one of the indicators 1024.

The communication interface 1032 interfaces to one or more types of communication systems. In one embodiment, the communication interface 1032 is a USB interface. In another example, the communication interface is an RJ-11 or RJ-14 telephone jack interface. In another example, the communication interface is an RJ-45 connector. In another example, the communication interface 1032 is an Ethernet-based interface. One or more of the previously referenced communication interfaces and/or one or more other interfaces may exist in a single embodiment. Other examples exist. The communication interface 1032 is optional in some embodiments.

The processor 1002 controls the operations of the ASPS 102G. The processor 1002 controls the on and off states of the AC receptacles 1014 by enabling and disabling the optical relay 1010 to connect and disconnect the AC input power for output to one or more AC receptacles. The processor 1002 transmits one or more signals to the optical relay 1010 to make or break a connection for one or more of the AC receptacles 1014.

The processor 1002 controls the on and off states of the DC receptacles 1030. The processor 1002 controls which DC receptacles 1030 will be enabled with DC power. The processor 1002 determines the DC power level that will be output from the DC to DC regulator 1018 for each DC receptacle. The processor 1002 transmits a signal to the DC to DC regulator 1018 identifying the DC power level to be output to each DC receptacle and enables the DC power output level for that DC receptacle.

The processor 1002 controls the transmission and reception of data to and from the modulator 1020. The processor 1002 receives data from the modulator 1020 and processes the data. The data may include, for example, a specific or approximate DC voltage level required by an electrical device connected to one of the DC receptacles 1030 and/or an identification of the electrical device.

The processor 1002 determines the type of communication that will be made via the modulator 1020. In one example, the processor 1002 controls the modulation of the modulator 1020 so that communications are made in a format receivable by the electrical device connected to the DC receptacle 1030. The processor 1002 also controls demodulation of the modulator 1020 so that communications received from an electrical device are transmitted in a format receivable by the modulator 1020 and processable by the processor 1002.

The processor 1002 controls the indicators 1024. The processor 1002 transmits one or more signals to one or more of the indicators 1024 for an indicator status. In one embodiment, the indicators 1024 are LEDs, and the processor 1002 enables a particular input to cause the LED to turn on. In another example, the processor 1002 enables another input of the LED to cause the LED to light a second color.

The processor 1002 controls start-up of the ASPS 102G. In addition, upon receiving a reset signal from the reset controller 1026, the processor 1002 retrieves the start-up programming from memory 1022 and resets the ASPS 102G.

The processor 1002 processes communications received via the modulator 1020 and the communication system 1028. The processor 1002 also transmits communications via the modulator 1020 and the communication system 1028.

In one embodiment, the processor 1002 generates a user interface via the communication system 1028 for display, such as for display on a computer system with a monitor. In this embodiment, the processor 1002 transmits data to the computer system for display. The data may include, for example, voltage levels required for a particular DC receptacle 1030, instructions to enable a particular DC receptacle for a particular level, instructions to enable or disable one or more AC receptacles 1014 and/or DC receptacles 1030, or other data.

In another embodiment, the user interface resides on a computer system that is communicating with the processor 1002 via the communication system 1028 and the communication interface 1032. In this embodiment, the processor 1002 transmits data to the computer system for display by the user interface. The computer system transmits data received from the user interface to the processor 1002 for processing. In this example, the data may include, for example, voltage levels required for a particular DC receptacle 1030, instructions to enable a particular DC receptacle for a particular level, instructions to enable or disable one or more AC receptacles 1014 and/or DC receptacles 1030, or other data.

In one embodiment, the processor 1002 monitors the output from the DC to DC regulator 1018 to identify the actual or approximate actual voltage being generated from the DC to DC regulator to a selected DC receptacle 1030. The raw analog voltage level generated by the DC to DC regulator 1018 is used as a feedback signal and is input back to the processor 1002. This feedback signal is indicated by the dashed-line between the processor 1002 and the DC to DC regulator 1018 in FIG. 10. In this embodiment, the processor 1002 has a voltage divider that divides the feedback signal to a lower DC voltage range, such as between 0 volts and 5 volts, samples the divided feedback signal with an analog-to-digital converter, and uses the sampled feedback signal to determine if any adjustments must be made to the output of the DC to DC regulator 1018 to maintain the proper output DC voltage. In one example, the voltage divider is a circuit having two resistors.

In one embodiment, the processor 1002 transmits an adjustment signal to the DC to DC regulator 1018 to adjust its output of a DC voltage for a particular DC receptacle 1030. In one example, the adjustment signal is an analog output signal that is used to inject an offset into the DC to DC regulator 1018. In this example, the degree of offset is linearly related to the output DC voltage of the DC to DC regulator 1018. This voltage may be expressed as Voutput=Vadjustment*Beta, with Beta=GainFactor+Tolerance. The GainFactor is a gain specific to the DC to DC regulator 1018, and its value depends upon the exact design of the DC to DC regulator. The Tolerance is a parameter used to express the production tolerance of each DC to DC regulator. Ideally, the Tolerance is 0.

The feedback loop signal enables the processor 1002 to vary Vadjustment until Voutput is equal to the DC voltage required by the electrical device connected to the particular DC receptacle. In other embodiments, the adjustment signal includes a raw digital format, rather than an analog format. Other examples exist.

In one embodiment, when an electrical device is connected to one of the DC receptacles 1030, the processor 1002 causes a minimal level of DC power to output from the DC to DC regulator 1018 to the DC receptacle. The minimal power level is enough DC power to initiate operations of the electrical device, such as operation of the electrical device's processor, but not enough DC power to fully power the electrical device. The minimal power level is low enough that it will not exceed power levels that may damage the electrical device. In this example, the minimal power level enables the processor of the electrical device to communicate with the processor 1002 of the ASPS 102G. The processor of the electrical device then is able to transmit the voltage requirements or the electrical device's identification to the processor 1002 of the ASPS 102G. The processor 1002 then configures the DC voltage level to be output from the DC to DC regulator 1018 to the DC receptacle 1030 in which the electrical device is connected and enables output of the DC power to that DC receptacle.

FIG. 11 depicts another exemplary embodiment of a ASPS 102H. In the embodiment of FIG. 11, the ASPS 102H includes DC receptacle 1 1030A through DC receptacle N 1030B. Each DC receptacle 1030A-1030B has an associated detector 1102-1104, such as a detector switch for the barrel connector described above. Other examples exist. Each detector 1102-1104 is configured to enable a signal to the processor 1002A identifying that an electrical device connector has been connected to the receptacle 1030A-1030B.

A modulator 1020A-1020B is configured to communicate between a respective DC receptacle 1030A-1030B and the processor 1002A. The processor 1002A transmits communications to the DC receptacles 1030A-1030B via the modulator 1020A-1020B and receives communications from the DC receptacles via the modulators.

A low current driver 1106 and 1108 and a high current switch 1110 and 1112 are associated with each DC receptacle 1030A-1030B. The low current drivers 1106 and 1108 receive DC power from the DC to DC regulator 1018A-1018B at a low current level and/or a low voltage level. The low current drivers 1106-1108 provide the DC power to the DC receptacles 1030A-1030B. The low current driver 1106-1108 is used to signal to the electrical device connected to the DC receptacle 1030A-1030B that the processor 1002A will transmit communications to, or receive communications from, the electrical device. In one embodiment, a low current driver 1106-1108 includes one or more resistors.

The high current switches 1110-1112 receive DC power from the DC to DC regulator 1018A-1018B at a high current level and/or a high voltage level. The high current switches 1110-1112 provide the DC power to the DC receptacles 1030A-1030B. The DC power provided by the high current switch 1110-1112 to the DC receptacle 1030A-1030B is used to charge or otherwise power the electrical device connected to the DC receptacle. In one embodiment, a high current switch 1110-1112 includes a transistor or multiple transistors configured to receive DC power from the DC to DC regulator 1018A-1018B and to receive an enable signal from the processor 1002A. Upon receiving the enable signal from the processor 1002A, the high current switch 1110-1112 transmits the DC power to the DC receptacle 1030A-1030B.

In the embodiment of FIG. 11, the processor 1002A and the modulators 1020A-1020B are configured to communicate using voltage modulation. In one embodiment, the modulator 1020A-1020B transmits communications to, and receives communications from, the DC receptacle 1030A-1030B using a hexadecimal format. In one example, one or more communications transmit ASCII-based characters using hexadecimal format.

In one embodiment, the ASPS 102H of FIG. 11 operates as follows. The DC receptacle 1030A includes a female barrel connector having a ground pin, a power pin, and a switch pin. The detector 1102 is the switch pin and switching mechanism in this example.

When a mating jack is not connected to the DC receptacle 1030A, the switching mechanism causes the switch pin to be connected to the ground lead. The switch pin also is connected to an input of the processor 1002A. When the switch pin is connected to ground, the processor reads the switch pin signal as a logic 0, which corresponds to ground.

An electrical device having a male connector is plugged into the DC female barrel connector receptacle. When the device is connected, the switch lead of the detector 1102 is disconnected from the ground lead. In this example, pull-up resistors are connected to the switch lead between the detector 1102 and the processor 1002A. When the switch lead is disconnected from ground, the detector signal transitions to a logic 1.

When the detector signal transitions to a logic 1, the processor 1002A determines that an electrical device is connected to the DC receptacle 1030A. The processor 1002A causes a low current and/or a low voltage driver signal to be generated from the DC to DC regulator 1018A through the low current driver 1106 to the DC receptacle 1030A. In this example, the low current signal is 24 volts DC and less than 5 milli-amps. The low current signal is enough power to turn on a processor for the electrical device. However, the low current signal likely does not have sufficient amperage to damage the electrical device.

The low current driver signal is an indication to the electrical device that one or more communications will be transmitted from the ASPS 102H to the electrical device. The processor 1002A transmits a query to the electrical device through the modulator 1020A and to the DC receptacle 1030A. In this example, the modulator 1020A uses voltage modulation to transmit the communication.

After the low current driver signal has been transmitted to the electrical device, the processor 1002A causes the modulator 1020A to transmit the communication to the electrical device through the DC receptacle 1030A. In this example, the processor 1002A transmits a series of enable and disable signals to the modulator 1020A. In response to the enable signals, the modulator 1020A outputs a voltage having an amplitude greater than a minimal amperage, such as 3 volts DC. The electrical device receives the voltage having the amplitude and recognizes it as a logic 1. When the modulator 1020A receives a disable signal, the modulator either outputs a voltage having a level below the minimal level or does not output any voltage at all. The electrical device identifies that the voltage is either below the minimal level or that no voltage is received at all and reads this as a logic 0. Using this method, a series of 1s and 0s are transmitted between the modulator and the electrical device as one more data packets.

The electrical device transmits a communication to the modulator 1020A through the DC receptacle 1030A, and the modulator transmits the communication to the processor 1002A. In this example, the processor 1002A has a divider circuit that divides the voltage of the communication to a lower voltage, such as voltage between 0 and 5 volts DC. The processor 1002A also has an analog-to-digital converter that samples the divided communication. The processor 1002A reads the converted signal and identifies the communication type and the data in the communication.

In this example, the communication from the electrical device is an acknowledgment indicating a status OK command. The processor 1002A transmits a message via the modulator 1020A requesting a voltage code and an identification string from the electrical device. The processor 1002A receives a communication from the electrical device via the modulator 1020A with the voltage code and the identification string for the electrical device.

The processor 1002A transmits a signal to the DC to DC regulator 1018A for the requested voltage and enables the output from the DC to DC regulator to the high current switch 1110. The processor 1002A also enables the switch for the high current switch 1110 which causes the DC power to flow from the DC to DC regulator 1018A through the high current switch 1110 and to the DC receptacle 1030A.

If the processor 1002A communicates with the electrical device while or after the electrical device receives the DC power generated from the DC to DC regulator 1018A through the high current switch 1110, the processor 1002A disables the output from the DC to DC regulator to the high current switch 1110. The processor 1002A may accomplish this by disabling the output from the DC to DC regulator 1018A, disabling the high current switch 1110, or both.

The processor 1002A then enables a low current and/or low voltage driver signal from the DC to DC regulator 1018A to the low current driver 1106. The low current driver 1106 transmits the low current driver signal to the electrical device through the DC receptacle 1030A. The low current driver signal is a signal to the electrical device that a communication will be transmitted from the processor 1002A. In this example, the processor 1002A and the electrical device operate in a master-slave relationship. In other embodiments, a polling relationship may occur between the processor 1002A and the electrical device. Other examples exist.

After the low current driver signal has been transmitted to the electrical device, the processor 1002A causes the modulator 1020A to transmit the communication to the electrical device through the DC receptacle 1030A. In this example, the processor 1002A transmits a series of enable and disable signals to the modulator 1020A. In response to the enable signals, the modulator 1020A outputs a voltage having an amplitude greater than a minimal amperage, such as 3 volts DC. The electrical device receives the voltage having the amplitude and recognizes it as a logic 1. When the modulator 1020A receives a disable signal, the modulator either outputs a voltage having a level below the minimal level or does not output any voltage at all. The electrical device identifies that the voltage is either below the minimal level or that no voltage is received at all and reads this as a logic 0. Using this method, a series of 1s and 0s are transmitted between the modulator and the electrical device as one or more data packets.

Similarly, in this example, the electrical device transmits one or more data packets to the modulator 1020A having a voltage amplitude that indicates a logic 1 or a logic 0. The voltage levels are transmitted from the modulator to the divider circuit and the analog-to-digital converter on the processor 1002A and read by the processor as a logical 0 or a logical 1.

The wall plug device 106A also includes a single electrical connector 1206. The electrical connector 1206 connects to a receiving connector 1208 in the line-cord device 104A. AC and/or DC power is transmitted from the line-cord device 104A to the wall plug device 106A via the electrical connector 1206 and the receiving connector 1208. In some embodiments, communications, including control instructions and/or data, are transmitted from the line-cord device 104A to the wall plug device 106A via the electrical connector 1206 and the receiving connector 1208. In one embodiment, the electrical connector 1206 is a 3-prong electrical plug. In other embodiments, other types of electrical connectors may be used.

FIGS. 23-43 depict an exemplary embodiment of a user interface (UI) 2302. The UI enables a user to determine if an electrical device is connected to the ASPS. In the embodiment of FIGS. 23-43, an electrical device is referred to as an automatic sensing-direct current and automatic synchronous-data communication (asDC) device, and the ASPS is referred to as an intelligent power hub.

The UI enables a user to select the voltage to be transmitted from the ASPS to an electrical device and to select the DC receptacle to which it will be generated. The UI also enables a user to turn one or more AC receptacles and/or DC receptacles on or off. For exemplary purposes, the UI of FIGS. 23-43 is directed to only one AC receptacle (identified as an AC port on the UI) and only one DC receptacle (identified as a DC port on the UI). However, other UIs may enable selection of multiple AC receptacles and multiple DC receptacles.

Additionally, a computer is connected to the power hub through a USB connection in the embodiments of FIGS. 23-43. The UI in this embodiment is generated through the host computer and displayable on the computer's display.

When the computer is not connected to the power hub, the UI indicates that no power hub is connected to the computer and no asDC device is connected to the power hub, as depicted in FIG. 23. When the power hub is connected to the computer, the UI indicates that the power hub is connected to the computer via the USB port, as depicted in FIG. 24.

As depicted in FIG. 25, when an asDC device is connected to the power hub, a window is displayed with the status change. The user selects the “OK” button on the status change window, and the status change window disappears. In other embodiments, the status window briefly appears and automatically disappears after a selected period of time. The asDC device status indicates that an asDC device was identified, as depicted in FIG. 26. The asDC device identification is specified by values in two fields, including a name or identity field and an operating voltage field. In the example of FIG. 26, the name or identity field may contain a string of up to forty characters. In this example, the device is identified as an “asDC Motorola 730” having an operating voltage of 5.29 volts DC. Other examples exist.

When the asDC device is disconnected from the power hub, a status change window is generated, as depicted in FIG. 27. The device status indicates that no asDC device is connected to the power hub, as indicated in FIG. 28.

An electrical device that is not configured to communicate with the power hub is referred to as a non-asDC device. If a non-asDC device is connected to the power hub, a status change window indicates that the non-asDC device is connected to the power hub, as indicated in FIG. 29. The status change window suggests that the user manually enable a DC receptacle.

The user may select a voltage to be output to a selected DC receptacle, as depicted in FIG. 30. In this example, the user selected the voltage level to be output to the selected DC receptacle. The user then selected the “force asDC port ON” to set the DC receptacle to the selected voltage level.

The user may elect to turn the AC receptacle on or off, as depicted in FIG. 31. If the user selects the check box for “AC port on/off,” the user may turn the receptacle on and off. When the AC receptacle is turned on, the power hub status window indicates that the AC port was enabled.

If the user again selects the check box for the AC port on/off, the AC power for the AC receptacle is turned off. The check mark from the check box disappears, and a new line is entered for the power hub status indicating that the AC port is disabled, as depicted in FIG. 32.

As depicted in FIGS. 33-34, the user turns the power on for the DC receptacle. In this example, the user selects a different voltage to be output to the DC receptacle. The user then selects the “force asDC port ON” check box. A check mark appears in the check box to indicate that the power is being transmitted to the DC receptacle. In addition, a line appears in the power hub status indicating that the DC port was forced on, as depicted in FIG. 34. In this example, the status line also indicates the code for the voltage and/or the device name.

The user may select the check box for the DC port again to force the DC receptacle off, as indicated in FIG. 35. A status line is generated to the power hub status indicating that the DC port was forced off.

The UI enables the user to update the firmware on the power hub, as indicated by FIG. 36. The UI enables the user to select from an open firmware option and a download firmware option. The open firmware option may be used to locate a file that is to be installed, as indicated in FIG. 37. The user selects the file to be opened, and the contents of the file are checked for integrity. If the integrity check is successful, an integrity check window appears and identifies the firmware as being valid, as indicated in FIG. 38. When the user selects the “OK” button from the integrity check status window, the firmware is opened and downloaded.

If the user selects the download firmware option from the display of FIG. 36, a status change window is generated indicating that the firmware download is starting, as depicted in FIG. 39. If the download process is successful, a status change window is generated indicating that the download is complete, as depicted in FIG. 40.

When the firmware has been downloaded, the user may select the reset on the power hub or cycle the power supply for the power hub by disconnecting the power supply from the power hub and reconnecting it. The user may relaunch the UI if desired.

A third option from the advanced menu option from FIG. 36 enables a user to change a target configuration of an asDC enabled device. When the user selects the change target configuration option from the menu, an update target properties window is generated for display, as depicted in FIG. 41. The user enters new values for the asDC device name and its operating voltage, as depicted in FIG. 42. When the asDC device is connected to the power hub, the power hub recognizes the device and its required operating voltage, as depicted in FIG. 43.

Those skilled in the art will appreciate that variations from the specific embodiments disclosed above are contemplated by the invention. The invention should not be restricted to the above embodiments, but should be measured by the following claims. 

1. A rack mount power system for configuring alternating current (AC) power, the rack power system comprising: a plurality of direct current (DC) receptacles; at least one AC receptacle configured to convey AC power at an AC power level; an AC to DC regulator configured to convert AC power to DC power; a plurality of DC to DC regulators, each corresponding to one of the DC receptacles and each configured to receive the DC power from the AC to DC regulator, to dynamically convert the DC power to a selected DC power level for the corresponding DC receptacle, and to generate the DC power at the selected DC power level for the corresponding DC receptacle, each selected DC power level independent of other selected DC power levels, each selected DC power level not selected from an initially preset conversion level; and a processor configured to determine each selected DC power level, to dynamically configure each DC to DC regulator to dynamically convert the DC power to the selected DC power level for the corresponding DC receptacle, and to enable generating the DC power at the selected DC power levels to the corresponding DC receptacles.
